COMBINED ROAD-G-RADER, DRAG, AND HARROW.

Application filed March 16 Specification of Letters Patent.

To all UJZLO'HL it may concern:

lie it known that I, Hana/r): DAVIS Gurrnr, a citizen of the UnitedStates, residing at Unionville, in the county of Putnam and. State oflllissouri, have invented certain new and useful lnuproven'iei'its in aCombined Road-Grader, Drag, and Harrow; and I do declare the followingto be a full, clear, and exact description of the invention, such willenable others skilled in the art to which it appertains to make and usethe same.

'lfhis invention relates to improvements in combined road g aders, dragsand barrows.

'ihe object of the invention is to provide a machine of this characterwhich may be regulated for light or heavy work and which may be quicklytransformed from a road grader to a d rag or harrow.

A further object of the invention is to provide means whereby the draftconnections .may be regulated to change the position of the grader.

\l'ith thee and other objects in view, the invention consists of certainnovel feature;' of construction, combination and arrangement of parts aswill be described and particularly pointed out in the appended claims. i

In the accompanying drawings, Figure 1 is a. top plan view of theinvention arranged as a grader; Fig. 2 is a sectional View taken on theline i2-2 of big. 1, Fig. 3 is a tional view on the line 33 of Fig. 1..1' ig. L} is a plan view of the machine arranged for light work; Fig. 5is a similar view showing the machine arranged a barrow; and Fig. 6 alongitudinal sectional view of the machine in the form shown in l' ig.(5.

Referring more particularly to the drawings, 1 denotes the 'aper bladesor bars of the machine which are connected together at their upper edgesby a series of obliquely disposed connecting bars, 2, and are held inposition by a brace bar, The blades, 1, consist of a vertical portion,4-, at the upper and lower edges of which are formed. forwardlyprojectinginclined or beveled extensions, The b \-'eled sides or facesof said extensions n'iay be, if desired, provided with removable scraperplates, (1. and, if desired, similar plates, 7, may be removably securedto the rear side of the blades adjacent to their lower edges. The bladesmay also be provided on their lowe sides and adjacent to their forwardedges with metal shoes or plates, 8, the forward edges of which engage il l 1 I Patented Oct. 20, 1908. 1908. Serial In. 121,410

the lower edges of the front scraping plates,

(3, when. the latte are applied to the blades. Secured to the forwardend of the central connecting bar, is a clevis, 5), with which adaptedto be loosely connected by means of an eye, 10, a. draft tongue, 12' Thedraft tongue is provided on its lower side with a guard plate lii,between which, and the underside of the tongue, is pivotally mounted awhillietree or similar draft; device, ll, said whitlletree beingpivotally connected with the tongue by a pin or bolt, 15. On theopposite side of the tongue, adjacent to its rear end, areuilraftregulating hooks, in, to which are adjustably connected the forward endsof draft regulating chains, 17, the innercnds of which are connected tothe for- \\"ard.ends of the outer connecting bars, 2. ()n the outerconnecting bar, adjacent to one end of the blades, is secured a driversseat, 18.

Arranged between the ends of the blades at one side of the machine'is aspacing blorlr. 19, to the outer side of which is cured a guiding shoe,or landside, 20, the lower edge of which projects below the lower sidesof the blades and is adapted to enter the ground and thereby guide orhold the machine to its work. The landside is fieferably removable andmay be detached from the machine when desired.

in Fig. of the drawings, the machine is shown as having the rear bladeremoved and the brace bar 3 connected at one end to one end of t toforward blade, and at its opposite end to the rear end of the connecting rod. at the opposite side of the machine.

\Vhen arranged in this positiom-the grader is adapted for use inconnection with light work. When the parts are arranged in the positionshown in Fig. 5, the device may be employed as a harrow, and when soused is provided with a supplemental tooth bar, 21, which is bolted orotherwise secured to the rear side of the front blade and is providedthroughout its length with a series of herrow teeth which project belowthe forward blade in position to enter the ground. The

connecting bars, 2, are preferably provided with a series of apertures,22, adapted to re ceive barrow teeth, 23, which are detachably securedin any suitable manner.

In the normal working position of the machine, as shown in Fig. 1, thedraft regulatin' chains, 17, are connected loosely to the draft-hooks,l6. lVhen, however, it is desired to change the position of the grader,or scrape more or less dirt in either direction, the chain on one sideor the other of the tongue is shortened by connecting one of the rearlinks with the hook, while the chain on the opposite side is slackened.

Frdm the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood withoutrequiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstructionmay be resorted to without departing from the principle orsacrificing any of the advantages of the invention as defined in theappended claims.

Having thus described my invention, what 1' claim as new and desire tosecure by Lettors-Patent, is:

1. A combined road grader, drag and harrow comprising transverselydisposed blades, a landside removably attached between the ends of theblades at one side of the grader, and means whereby the position of thegrader may be changed to throw the dirt to either one side or the other.

2. In a machine of the character described, transversely disposed bladeshaving along their upper and lower edges forwardly projecting beveledextensions, a landside adapted to be detachably secured between the endsof the blades, at one side of the machine, a

loosely connected draft tongue, and detachblades in operative position,a draft hook ans tongue loosely connected to said drafthook, draftregulating chains connected to the opposite ends of the grader and tosaid tongue, and a landside secured to the ends of said blades along oneside of the machine, substantially as described.

4. A machine of the character described comprising transversely disposedblades, aseries of connecting bars, said bars having formed thereinaseries of harrow teeth assages, a brace bar, a landside arran ed a ongone side of the grader, a detaehab e harrow bar, a draft tongue, andmeans to connect the machine with said ton ue whereby the position ofthe former maybe changed, substantially as described.
